Total organic carbon (TOC) testing is the traditional method for determining organic matter in water. However there is a far more practical, affordable and often more useful way to measure organic matter. UV absorbance testing (UVA) is rapidly becoming the preferred method of measuring organics even when the levels of organics being measured are very small. Organic Matter Organic ...

Global warming due to the excessive use of fossil fuels is becoming a problem which has prompted and accelerated the search for alternative fuels. Among the more attractive alternatives is biomass fuel, which is attracting considerable attention. Microalgae can be used for the production of oil without competing with food production, and to a greater extent than other biofuels, its ...

As other industrial devices airports have to control their run-off weter for TOC and/or COD. The amount of waste water produced at airports is not negligible: The Frankfurt airport (one of the biggest airports in Europe) has produced 1.63 million cubic meters in 2006, the same amount as a medium-sized city. The sewer system of this airport consists of a 200km tubing system with a low quantity of ...

During winter, de-icing processes at airports necessitate storm water and de-icing water management. Especially due to adhesive (sticky) substances, strongly fluctuating concentrations and a lot of chemicals, the monitoring systems itself must be tailor-made to fight this water analysis challenge. LAR 's ...

The case study outlines the installation of Protoc TOC analysers at Manchester International Airport used for continuous surface water quality monitoring and control. The Protoc TOC instrument manufactured in the UK by Pollution & Process Monitoring Ltd was rigorously tested and was selected for a number of installations at critical drainage locations which have proved the reliability of the ...

At wastewater treatment facilities of various types of manufacturing plants, pollution load monitoring (upstream monitoring) is becoming increasingly important to ensure appropriate and stable operation and water pollution accident prevention. Pollution load varies depending on the operating status of the plant, so continuous monitoring is essential. Continuous and stable ...

The quantity of organic matter in seawater is important in the research and monitoring of marine pollution as an indicator of organic pollution. The salt content in seawater is typically about 3.5 %, but using the Shimadzu total organic carbon analyzer, it is possible to measure the TOC directly without dilution or other pretreatment procedures. Here, we introduce an example of measurement of ...

Overview Wastewater is used water. It can include substances such as human waste, food scraps, oils, soaps, and chemicals. Manufacturing industries as well as wastewater municipalities must comply with the United States Environmental Protection Agency’s (USEPA) Clean Water Act (CWA) regulations. In order to discharge treated wastewater and be compliant with the CWA, a ...

Background A boiler system is a semi-closed loop system in which water is heated and converted into steam to power a generator. The steam is then allowed to form a condensate and the process is repeated. Boiler water chemistry directly impacts boiler efficiency and fuel use. Improper water treatment allows scale formation and corrosion. Boiler scale and deposits form when impurities ...

Executive Summary Steam in petro/chemical plants could be contaminated with hydrocarbons (TOC = Total Organic Carbons) from various sources. In any case this is a sign for defects in the process, whether it they occur in the heat exchanger, the blow down vessel, the condensate recovery or other parts of the system. Conventional solutions to monitor such contaminations use TOC- ...

What You Need to Know Analytical laboratories in the chemical industry are routinely tasked with monitoring organics in water across a wide range of applications. For example, organic carbon analysis is being used to: Monitor plant storm water and wastewater Test for condensate system or boiler integrity Enhance cooling and make-up water quality ...

LAR Process Analysers AG of Berlin, Germany expanded the range of feaiures of its measuring device QuickTOC, which facilitates the monitoring of ultra pure and cooling water, boiler feed and condensate measurement, and industrial wastewaters. For many years, the Berlin company lias been developing, high quality measuring devices and processes for the TOC analysis of condensates and boiler ...

A food manufacturing facility in Selby has installed a new continuous TOC (Total Organic Carbon) monitor, ‘the BioTector’ which has dramatically improved the site’s capability to refine and improve the plant’s wastewater treatment process. As a result the plant is better able to quickly respond to changes in the influent. Greencore Foods is a leading player in the food ...

The control of waste water treatment plants is of special importance - from an ecological as well as economic point of view. The most common water parameters for controlling and optimization are the total organic carbon (TOC), chemical oxygen demand (COD), total nitrogen bound ( ...

Introduction The role ofthe plants providing water is not restricted to the collection of water from areas where abundantly available and then distribution to the consumer. In reality, it involves a serious commitment to the guarantee of waterwhich is high quality. For this reason, drinking water facilities make use of conditioning plants which are equipped with chemical lab ...

The case study outlines the installation of Protoc TOC analysers at Heineken used for monitoring key effluent streams and proactively manage their site effluent. After ten years of continuous operation, the instruments are still performing reliably and are an integral part of the Company’s environmental compliance. The site has used the Protoc analysers to gain a better understanding of ...

Industrial wastewater is a result of manufacturing, agricultural, environmental, and research activities. Managing the treatment and discharge of industrial effluents is a critical process that ensures compliance with regulatory ordinances, upholds public health and safety, and guarantees the protection of natural and public resources. Classical processes are typically employed to deal with ...

In 2006, the USEPA singled out the distribution system as the most vulnerable component of a utility’s drinking water system. In response, many waterworks are taking a closer look at how they may protect the public’s drinking water. One option is to place online water quality panels throughout the distribution system to detect a change in the baseline water quality. The cost of implementing a ...
